Polybius gives a description of how scipio stormed New Carthage ( Qart-Hadasht )

When Scipio thought that a sufficient number of troops had entered he sent most of them, as is the Roman custom, against the inhabitants of the city with orders to kill all they encountered, sparing none, and not to start pillaging until the signal was given. They do this, I think, to inspire terror, so that when towns are taken by the Romans one may often see not only the corpses of human beings, but dogs cut in half,

According to Cicero, while at the court of Antiochus, Hannibal attended a lecture by Phormio, a philosopher, that ranged through many topics. When Phormio finished a discourse on the duties of a general, Hannibal was asked his opinion. He replied, "I have seen during my life many old fools; but this one beats them all."
